Application iiledfApril 17,1901.. Serial No; 56,285. (No model.)

To @ZZ whom t may concern:

Be it known that I, PETER T. REYNOLDS, a citizen of the United States, residing at Butte, in the county of Silverbow andy State ofMontana, have invented a new andiuseful Mine- Ventilator, of Vwhich the'following is a' specification.

My invention relates to apparatus for cooling fluids, and especially for cooling the air supplied to the lower levels of mine workings to render the atmosphere in said workings of a sufficiently low temperature to enable those there employed to work without discomfort.

To this end my invention consists of the novel arrangement of air-supply pipe,expand ing-chamber, cooling-passages, freezing-mixture tank, and current-deflectors hereinafter set forth, particularly described, and claimed.

My invention is illustrated in the accompanying drawings, in which- Figure l is a sectional plan view of my device; Fig. 2, an elevational view 'in section of same, taken on line ai of Fig. l; and Fig. 3, an end view showing end wall D broken away.

Referring to the drawings, A is an air-supply pipe; B, an expanding-chamberyC, a`

cooling-mixture tank; D, an end wall;v E E, tubes rotatably mounted in walls Fand G,

H H, projecting outlet-spouts of tubes E E,-`

and I a door giving access to tank C.

The particular construction and operation of my device are as follows: Air is supplied through a pipe A and is traveling in said pipe under more or less compression and high y speed. The pipe A opens into the expanding-chamber B, where the air expands to a certain extent, producing a cooling eect upon itself. The wall F of the expandingchamber B also forms the end wall of the cooling-mixturetank C. The wall F is provided with a plurality of holes arranged in vertical series, which correspond with registering holes in the other end waliGpof the coolingmixture tank. Re'volubly mountedin thesev registering holes are tubes E E, which pass through the cooling-mixture tank C and extend or project beyond the wall G. These projecting portions of the tubes E E are bentat an angle from their axes and form spouts I-I I-I. That portion of each of the tubes E E which is within the cooling-mixture tank C is bent in a` series of sinuous bends in the same plane, which increase the cooling-surface of the tube andform the inner surface in such a manner that the air passing through is constantly agitated and'thrown against the walls ofthe tube. Thesinuous bends being inthe same plane allow the tubes to offer the least obstructing surface whenvthetubes are rotateduntil the lbends assume a vertical position to the icing of `the' cooling-mixturetankgfrom the door I in the top of the tank. The tubes also being the series will be unobstructed clear to the bottom of the tank. The projecting spouts being bent at an angle from the axes of the tubes allow the issuing air to be projected in a wide range of direction by simply turning the tubes until said spouts point in the desired direction. The spouts I themselves serve as handles by which the tubes may be turned or revolved, the bend at the spouts I serving as a crank portion. A further advantage of this construction is that the cooling mixture, ice, dac., in the tank C when it becomes caked may be shaken down to make room for more by simply revolving the severaltubes by their spouts I. The feature of projecting the issuing air-current in different directions without moving the tank is very desirable when the device is putin use in the deepV workings of mines and the like. The simplicity of this construction and the variety of useful functions performed by it will appeal to all.

It is obvious that I may vary the details of out departing from the spirit of myinvention.

Having described the several parts of my device and its operation, what I claim isl. In a fluid-cooling device, the combination with a duid-supply pipe and a coolingmixture tank, of a rotatable tube passing through the interior of and passing through and. journaled in the walls ofv said cooling- `mixture tank, said tube within theinterior of said tank provided with 'a series of sinuous bends in the same plane, one end of said tube communicating with said supply-pipe and the other end of said tube communicating with the atmosphere, substantially as described.

2. In a fluid-cooling device, the combinaarranged in vertical series,the spaces between' construction to suit varying conditions with-Y IOO tion With a Huid-supply pipe and a coolingmixture tank of a plurality of rotatable tubes arranged in vertical series passing through the interior of and passing through and journaled in the Walls of Said cooling-mixture tank, each of said tubes Within the interior of said tank provided with a series of sinuous bends in the same plane, one end of each of said tubes communicating with said sup- Io'ply-pipe and the other ends of said tubes communicating with the atmosphere, substantially as described.

In testimony whereof I have signed my name to the specification in the presence of tWo subscribing Witnesses.

PETER T. REYNOLDS.
